*graphic* Cause of death? Internal photos

[CoopBoots]

I'm not even going to call this a necroscopy; I was in a huge rush due to outside events but wanted to see if I could at least guess at cause of death. She appeared healthy around one to two hours prior.

Details: Dead in a spasm-like position (on side, both legs rather extended) in favorite dusting spot. Distended, fleshy, egg shaped protrusion from clean vent. Mouth revealed small amount of brownish-clear mucous.

Protrusion, which I later discovered was a soft shelled egg:

I plucked the breast/stomach and there appeared to be bloody fluid darkening the bottom-right (my right as I looked at her) of her body:

Opening her up revealed a lot of fluid, clearish pink:

Large red mass (unsure what I'm looking at here):

More photos as I tried to get to her reproductive areas (gizzard removed):

Is this another fatty liver scenario, assuming the organ in the middle of the last photo is the liver, coupled with a difficult egg/calcium deficiency that may have prompted the rupture?

Open to any thoughts. She was a year and several months old; my top hen. Latest of three deaths in my Hoovers Buff Orpington flock since I started last year.

It looks like a fair amount of fat... was she a plump chicken? If she was obese it could have been fatty liver disease with a hemorrhage...
There was a recent post with a similar looking scenario:
